一种先进运动估计算法的硬件实现

An Advanced Hardware Realization of Motion Estimation

文中介绍了一种先进运动估计处理(MEP)的算法实现。所介绍的MEP用于图像间的运动估计,它计算参考图像在搜索图像区域中不同位移时,两幅图像对应像素点亮度信息的差值之和,并选取最小值作为运动向量。而其硬件实现则采用较先进的处理单元阵列,外挂DSP处理器和外置SRAM存储器,所以算法处理速度可以迅速加快,相反硬件实现的面积也较小。

An advanced hardware realization technique of motion estimation between two images,materially is realized by choosing a better motion vector, which is the smallest one of all the sums between two relative piels belonging to two images separately while computing the motion vector of referencing image in searching image field.So its compute speeds up and realization area is relative small by adopting advanced processor element arrays and external dsp and sram.
